Really funny game! I really like how you interpreted the theme =)!
Your gameplay loop is simple, but very addictive! It was very enjoyable to go through the levels ^^. The difficulty curve is nice (maybe a bit too easy, but for a jam, it's better than being too hard), and the skill ceiling is high enough to make the game fun despite the repetitiveness! Just one small nitpick, my first instinct was to avoid bananas with the bike, but then I discovered that it could crush them. I feel like it made the game really easy, because I was nearly never on foot.
The graphics are amazing! I loved the style and everything looked really polished! The explosions, the trails, the little bubbles... You didn't have to do all that for a jam game, but I'm really happy you did =)
The sound design is really fitting! The ambiant sounds, the weird music, and the fact that every action has a sound feedback is really well done.
So... Yeah, overall a great concept with really good execution, congrats ^^ !
